SPECIFICATION forming part of Letters Patent No. 635,431, dated October 24., 1899.

Application filed December 12,1898. Serial N0.698,9'79. on model.)

To all whom, it may concern-.-

Be it known that I, ALEXANDER DOM, a citizen of the United States, residing at Hartwell,

in the county of Hamilton and State of Ohio,

have invented certain new and useful Improvements in Binding-Files, of which the following is a full, clear, and exact descrip tion, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of binding-files composed of a base-piece from which extend at right angles thereto and near the top edge thereof two filing-rods, upon which the leaves or other papers to be filed are strung, and which are secured in place by a sliding top piece or follower, usually in the form of a hinged book-cover, and provided with means for locking the same to the filingrods when pressed down upon the leaves and for unlocking the same to permit it to be raised and removed from the rods to introduce new leaves'or change theirrelative positions on the rods.

It has for its object the improved and simplified construction of such binders, whereby their cheapness and efficiency of action are increased.

The novelty of my invention will be hereinafter more fully set forth, and specifically pointed out in the claims.

In theaccompanying drawings, Figure 1 is a perspective view of a binding-file embodying my invention. Fig. 2 is an enlarged detail sectional elevation of the locking and releasing mechanism of the follower, together with portions of the filing-rods. bottom plan View of the cover of the locking and releasing mechanism box, together with the parts carried thereby. Fig. 4 is an enlarged transverse section on the dotted line w a: of Fig. 2, looking to the right. Fig. 5 is an enlarged plan view of one end of the bottom of the box portion. Fig. 6 is a corresponding view of one of the clamping-arms. Fig. 7 is a perspective view of a modification in the constructionof the campiece.

The same letters of reference are used to indicate identical parts in all of the figures. A represents any suitable base, preferably in the form of a rigid book-back, from which Fig. 3 is av tom piece F, with perforations through the top and bottom of the box and through the part D for the free passage of the rods B in such manner that the cover, with its extension D and box E F, can freelyslide up and down on the rods and can be lifted off of the same when it is desired to file new papers or remove old ones, after the manner of files of this character. Pivoted within the box at or near its middle and preferably to the top E, as at c, is a double cam-lever G, Figs. 2 and 3, Whose inclined ends engage two clampingpieces H, fulcrumed, as at d, upon the bottomof the box, in this instance to upturned cut-out portions 6, Figs. 2 and 5. The outer ends of the levers H have perforations f through them for the passage of the rods B and springs g within the box, and bearing upon the outer ends of the levers h cause them to be tilted in such manner that the edges of their perforations f pinch or bind upon the posts B to hold the cover 0, with its extension D, looked upon the rods B, and thereby bind the leaves filed upon the rods B firmly between the extension D and the subjacent end of the base A, as will be readily understood.

A slot 1' is formed through the top of the box, through which projects a thumb-piece j, Figs. 1 and 2, bypressing upon which the lever Gis turned, and the inner ends of the levers H are pressed down, thereby tilting the same to a horizontal position and holding the same in such position, so that the cover 0, its extension D, and the box may freelybe raised or lowered upon or entirely removed from the rods B. When the extension D is pressed down to bind the leaves, the piece j is pressed in the opposite direction to swing the lever G on its pivot, thereby releasing the inner ends of the levers H, and thereby permitting the springs gto come into action to tilt them ICO and cause their perforationsfto pinch upon the rods B and thus lock the cover to the rods, as will be readily understood.

\Vhile I prefer the use of the springs g for operating the clamping and releasing levers in one direction, yet they may be dispensed with and the clamping-levers be operated positively in both directions from one end. To accomplish this, Iprovide a cam-piece G, having at its ends inclined slots Z, in which the inner ends of the levers H are loosely confined, so that by vibrating the cam-piece G the clamping and releasing levers are operated positively in both directions and the springs may be dispensed with, as will be readily understood.

Having thus fully described my invention, I claim 1. In a binding-file, the combination of a filing-base, a pair of filing-rods extending therefrom, at right angles thereto and parallel with each other, a clamping-piece with perforations fitting overand sliding upon said rods, a cam-lever carried by said clampingpiece, vertically-tilting levers with perforations engaging the filingrods one end of said levers being engaged by the cam-lever,whereby when the cam-lever is turned the perforated levers are vibrated to pinch the rod. substantially as described.

2. In a binding-file, the combination of a filing-base, a pair of filingrods extending therefrom at right angles thereto and parallel with each other, a clamping-piece with perforations fitting over and sliding upon said rods, a housing upon said clamping-piece, a cam-lever within the same with exterior operating means, vertically-tilting levers with perforations engaging the tiling-rods one end of said levers being engaged by the cam-lever and their opposite ends being'engaged by springs,whereby when the cam-lever is turned in one direction the springs cause the perforated levers to tilt and pinch upon the filingrods and lock the clamping-piece thereto, and whereby, when the cam-lever is turned in the opposite direction the perforated levers are released from the filing-rod to permit the clamping-piece to be raised and lowered on or removed from said rod, substantially as described.

3. In a binding-file, the combination of a base, a pair of filing-rods extending therefrom at right angles thereto and parallel with each other, a clamping-piece with perforations fitting over and sliding upon said rods, a box upon said clamping-piece with perforations for the passage of the filing-rods, a cam-lever pivoted within said box with exterior means for operating the same, vertically-tilting levers Within said box having perforations en-' gaging the filing-rods, one end of said levers being engaged by the cam-lever and their opposite ends being engaged by springs within the box,whereby when the oann-leveris turned in one direction the springs cause the perforated levers to tilt and pinch upon the filingrods and lock the clamping-piece thereto, and whereby, when the cam-lever is turned in the opposite direction the perforated levers are released from the filing-rods to permit the clamping-piece to be raised and lowered on or removed from said rods, substantially as described.
